PHP学习 mysqli预处理查询结果集

$mysqli=new mysqli("localhost", "root", "123456", "xsphpdb");


$stmt=$mysqli->prepare("select id, name, price, num, desn from shops where id>?");


$stmt->bind_param("i", $id);


$stmt->bind_result($id, $name, $price, $num, $desn);


$id=99;


$stmt->execute();

$stmt->store_result(); //一次性将结果都取过来 重要


//字段信息
$result=$stmt->result_metadata();

while($field=$result->fetch_field()){
echo $field->name."--";
}
echo '
';
//记录信息
//$stmt->data_seek(2); 
while($stmt->fetch()){
echo "$id--$name---$price---$num---$desn
";
}


echo "记录总数：".$stmt->num_rows;


$stmt->free_result();


$stmt->close();
